Auto ISO Sensitivity Control (P, S, A, and M Modes Only)

If On is selected for ISO sensitivity settings > Auto ISO sensitivity control in the shooting menu, ISO sensitivity will automatically be adjusted if optimal exposure can not be achieved at the value selected by the user (ISO sensitivity is adjusted appropriately when the flash is used).

1 Select Auto ISO sensitivity control for ISO sensitivity settings in the shooting menu.

To display the menus, press the Gbutton.

 

Select ISO sensitivity settings in the

Gbutton

sensitivity control and press 2.

 

2Select On.

Highlight On and press J(if Off is selected, ISO sensitivity will remain fixed at the value selected by the user).

3Adjust settings.

The maximum value for auto ISO sensitivity can be selected using Maximum sensitivity

(the minimum value for auto ISO sensitivity S is automatically set to ISO 100; note that if

the value selected for Maximum sensitivity

is lower than the value currently selected for ISO sensitivity, the value selected for Maximum sensitivity will be used). In modes P and A, sensitivity will only be adjusted if underexposure would result at the shutter speed selected for Minimum shutter speed (1/2000–1 s, or Auto; in modes S and M, ISO sensitivity will be adjusted for optimal exposure at the shutter speed selected by the user). If Auto (available only with CPU lenses; equivalent to 1/30 s when a non-CPU lens is used) is selected, the camera will choose the minimum shutter speed based on the focal length of the lens (auto shutter-speed selection can be fine- tuned by highlighting Auto and pressing 2; for example, even faster values than those usually selected automatically by the camera can be used with telephoto lenses to reduce blur). Shutter speeds slower than the minimum value may be used if optimum exposure can not be achieved at the ISO sensitivity value selected for Maximum sensitivity. Press Jto exit when settings are complete.
